To answer my own question and for others that might want to do the same:

# Cmake only adds the default package target if a package config file
# named CPackConfig.cmake exists in the outermost binary build directory.
# By forcing the CPack module to generate the package file under a
# different name, we prevent the "target" path from being generated.
SET( CPACK_OUTPUT_CONFIG_FILE "${CMAKE_BINARY_DIR}/BundleConfig.cmake" )
include(CPack)

ADD_CUSTOM_TARGET( bundle
            COMMAND "${CMAKE_CPACK_COMMAND}"
                     "-C" "$<CONFIGURATION>"
                "--config" "${CMAKE_BINARY_DIR}/BundleConfig.cmake"
                COMMENT "Running CPack. Please wait..."
                DEPENDS ${PROJECT_NAME})

IF (WIN32)
    ADD_CUSTOM_COMMAND( TARGET bundle
                   POST_BUILD
                   COMMAND ${CMAKE_COMMAND} -D 
CMAKE_SYSTEM_NAME=${CMAKE_SYSTEM_NAME} -D VERSION=${VERSION} "-P" 
"${CMAKE_CURRENT_SOURCE_DIR}/../../chocolatey/mrViewer/CMakeLists.txt"
                WORKING_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}"
                  )
ENDIF( WIN32 )

This works in that instead of calling make/ninja package you call 
make/ninja bundle.
